    parser.c: xmlParseCharData peek behavior fixed wrt newlines
    
    Previously, xmlParseCharData and xmlParseComment would consider 0xA to
    be unhandleable when seen as the first byte of an input chunk, and
    fall back to xmlParseCharDataComplex and xmlParseCommentComplex, which
    have different memory and performance characteristics.
    
    Fixes GNOME/libxml2#192
